The present invention covers an atomizer stopper designed for mounting on a phial containing a liquid product to be atomized.

The purpose of the invention is to create such an atomizer stopper which offers a perfectly regular shape when it is in its closing position, completely lhiding the atomizing device.

Another object of the invention is to create an atomizer stopper capable of being operated by depressing a cap sliding on a pump cylinder and of being locked in its lower position and extending a part in the shape of a sleeve, mounted on a socket, permanently secured to the neck of the phial in such a manner that the stopper appears with a perfectly continuous outer surface and an upper surface which can be completely smooth.

Another object of the invention is to create an atomizer stopper of the above type comprising a simple pump mechanism ensuring a perfect atomization of the liquid through a hole provided in a side wall oi the stopper.

r)The invention also aims at means which are completely hidden for introducingair into the phial and into the pump body.

Various other objects and advantages ofthe invention will become apparent from the iollowing detailed description.

Figure 6 is an outside view of the atomizer vstopper ready for operation. Y

Figure 7 is an outside view of the atomizer stopper, closed for transportation.

In Figure l, the atomizer stopper consists of a part I, offering a recess 2 at its lower portion; the edge of said recess is threaded inside. A recess 3 is provided in the upper portion of part I; the edge of this recess is threaded inside, A central along -channel d is drilled in the center of Vpart I and 2 ber l; this pipe is bored, at its center, with avertical channel Il] and on its side, with a small horizontal channel II placing the central vertical channel Ill in communication with the chamber i. A socket I2, threaded outside, is permanently sealed with cement on the neck of the phial containing the product to be atomlzed. i3, i3d, lh, designate grooves provided in the inner wall of the socket lil, facilitating the holding of the cement. This socket oiers, on the outside, a vent which allows a communication between the inside of the phial-on which it is secured and the outside, a hole being provided at the upper portion of the socket I2 which is screwed in the lower, recessed portion 2 of part I. I A stem I4 is screwed in the upper portion of the central tapped channel li.; said stem oifers a flange I5 limiting its engagement into the channel fi. A pump cylinder i6 is screwed, at its lower portion, into` the upper recess 3 of part I. This pump cylinder olers, at its upper portion, a rectangular hole 4l l. A rectangular rod I8 can slide inside the rectangular hole il and offers, at its base, a turned down portion I9 Von which is engaged a piston vcomprising a metal plate 2li, a leatherpart 2i,

anda cup shaped washer 22V holding the leather part 2I, the assembly of these three parts being locked on the turned down portion i9 of the rod I8 by a nut 23 screwing into a screwthread provided on the vturned down portion I9.Y

` The rod I8 offers a second turned down portion at its top; a stud 24 is placed in this turned down portion. A cap 25 offers a boss 26 at its center. The rod I8 is bored, at its center, by a channel 2 which allows it to slide freely on the stem I4. The cap 25 is secured on the piston I8 by forcing in of the boss 26 into the channel 21; a helical spring 28 is placed in the pump cylinder I 6. This spring bears, on one hand, on the bottom of the upper recess 3 of part I, and, on the other hand, against the cup shaped washer 22 supporting the pump leather 2 l. 29, Sli, designate the vent holes of thepump body; a capillary tube (not shown in the drawing), dipsinto the liquid to be atomized and is screwed by its upper portion in the central tapped channel 4.

The atomizer stopper operates in the following manner:

The socket I2 being sealed on to the neck of the phial containing the liquid to be atomized, the atomizer stopper, on `which is mounted the capii lary tube dipping into the liquid to be atomized is screwed thereon. Said liquid rises, due to capillarity, into the chamber l, through the channels t and 6; then the cap 25 is depressed. The air contained in the pump body l is expelled by the leather washer 2| into the channel lil of pipe 3, then passes through the capillary channel i and from there into the chamber 1 where it atomizes part of the liquid it contains, the whole issuing towards the outside through the channel 8.

The cap 25 is released and cornes back to its rest position under the action of the spring 28; air enters the pump body through the holes 23, 3|), and the phial through the passage provided between the socket i2 and the edge of the lower recess 2 of part then through the hole provided at the center of the socket I2. At the same time, some liquid iills the chamber 1. The atomizer is again ready to operate. Y

If it is desired to carry the phial provided with its atomizer stopper, the stopper 25 is pushed in, then imparted a rotation of a quarter turn for housing the upper edge i3d of the rod i8 under the upper porti-on of the pump body i5; the stud 24 limits the rotation of the cap; the whole then assumes the shape shown in Figure '1.

In Figure 2, the atomizer stopper is made up of a lower part 3i, comprising an upper recessed portion Sie, the edge ofV which 3&5 is tapped and a recessed lower portion 3 l c.

The central portion 32 is provided with a tapered conical hole 33 connecting the upper recess 3|a with the lower recess 3Ic. A part 34, the upper truncated conical portion 34a of which occupies the hole 33, comprises a lower cylindrical portion 34D, recessed, the inner `edge 34e of which is tapped. The part 34 is bored, at its center, with a tapped channel 35 and two channels 36, 31; the channel 36 is extended by a channel 38 bored into the part 3| and opening into a chamber 38a, the edge of which 38h is tapped; a channel 38e extends the channel 38 and places the chamber 38a in communication with the outside. this pipe is bored with a vertical channel 39a connected with the chamber 38a through a capillary channel 39h. f

A socket 4|), threaded outwardly, is sealed permanently with cement, on the neck of the phial containing the product to be atomized, 40a, 45h, 43o designate grooves provided in the inner wall of the socket 45, facilitating the holding of the cement. The socket 44 screws into the recessed,

tapped portion 34h of part 34. A sealing gasket 4| is interposed between these two latter parts. Part 3| is bored with a blind hole 42 in which a spring 43 is housed, pressing against a ball 44' which is placed in two semi-spherical recesses 44a, 44h provided in part 34 (Figure 3),. function of this device will be explained later on.

A pump cylinder 45 is screwed on the tapped portion 3|?) of part 3|; this pump cylinder contains a stem 46 screwed in the tapped channel 35 and offers a iiange 46a, holding a spring 41L which supports the part 34 inside the truncoconical hole 23 bored at the center of the part 3 I The upper portion 45a of the pump body, is bored with a rectangular hole 45D, through which can slide a rectangular rod 48, the lower portion of ywhich is turned down and threaded, said por-r A pipe 33 is housed in the chamber 33a;

Thel

channel 48C, and can thus slide on the stem 45. A cap 54 olers at its center a boss 54a, forced into the upper portion of the channel 43C bored into the rod 48. This cap may completely surround the pump body 45. 55 designates a spring bearing, on one hand, against the bottom 3|a of part 3|, and, on the other hand, on the cup shaped element 5|. This spring tends to push the rod 48 upwards, together with the leather washer 50 of the pump. 55, 56a designate the air vents of the pump. A capillary tube dipping into the liquid to be atomized contained in the phial on which the atomizer stopper is screwed is itself screwed by its lupper portion into the tapped channel 35. 31 designates a screw preventing the stem 43 from rotating.

The atomizer stopper operates as follows:

The socket being sealed on the neck of the phial containing the liquid to be atomized, the atomizer on which is mounted the capillary tube is screwed on it. The liquid rises, due to capillarity, up to the chamber 38a, going through the channels 36 and 38. The cap 54 is then depressed. The air contained in the pump body is expelled by the leather washer into the vertical channel 39a of the pipe 39, then passes through the capillary channel 39h into the chamber 38a, atomizing a certain amount of the liquid it contains; the atomized air and liquid mixture issues outwards through the channel 38e.

The cap 54 is released, and resumes its rest position under the action of the spring 55; some air enters the pump body through the holes 56, 55a and the phial through the passage provided between the parts 3| and 34, then through the channel 31 opening above the central hole provided in the socket 40. At the same time, some liquid iills the chamber 38a. kThe atomizer is again ready to operate.

If it is desired to carry the phial provided with its atomizer stopper, a rotation of one quarter turn, for instance, is given to part 3| with respect to part 34; the ball 44 then moves from one of the semi-spherical cavities to the other semi- Y spherical cavity (Figure 3). This motion is possible because the connection between the parts 3| and 34 is effected by the spring 41, which makes it flexible. Further, in View of the carrying of the phial, the cap 54 is pushed in, then given a rotation of a quarter turn, for instance, to house the edge 48d of the rod 48 under the upper portion 45a of the pump body 45. The stud 53 limits the rotation of the cap, and the whole then assumes the shape shown in Figure 6.

If it is desired yto use the atomizer again, the above-mentioned operations should be eected in the reverse order.

The atomizer stopper of Figure 4 is comprised of a lower part 60, comprising an upper recessed portion 6I, the edge of which Bia, is tapped and a lower recessed portion S2. The central portion 63 is bored with a trunco-conical hole 54 connecting the upper recess 6| and the lower recess 62. A part S5, the upper trunco-conical portion of which 33 occupies the hole 64, Vcomprises a lower cylindrical portion S1, recessed, the inner edge of which B8 is tapped. The part 65 is bored, at its centenwith a tapped channel 69 and two channels 10, 1|. The channel 1,0 is extended by a channel 12 bored into the part 60 and terminates intoY a flared portion 13, the edge of which 13a. is tapped. The trunco-conical portion 63 of the part 65 is drilled with a channel 14, bent at a right angle, and placing the recessed portion 6| and the flared portion 13 in communication. A socket 15, threaded outwardly is permanently sealed by means of cement on the neck of the phial containing the product to be atomized. 16, 16a, 1Gb, designate grooves provided in the inner `walls of the socket 75, iacilitat ing the holding of the cement. The socket "15 screws into the recessed and tapped portion l of the part d5, a sealing gasket 'il is interposed between these two parts. A pipe '18, bored with a central channel 18a, is secured by being forced on the end of the channel M and an end part '19 is screwed in the tapping 73a of the ared portion 13; this end part is bored with a channel 19a.

Two studs, Si), 3l, secured in the part 65 (Figure 5), act as stops for the stud .#32, secured in the body of the part 60. The channel ld is extended by a pipe 83. tapped portion i5 l a of the part 6d; this pump body contains a stem 35, screwed in the tapped channel 69 and oiers a flange 83, holding in position a spring 81 supporting the part inside the trunco-conical hole @d of the part iii). The upper portion of the pump body @d is bored with a rectangular hole 85, through which a rod 89 can slide, the lower portion of which is turned down and threaded, said portion receiving a metal disc 9B, a leather washer Si acting as a piston and a cup shaped element 52 holding the leather washer di. The assembly of these three parts is locked on the turned down portion of the rod @El by a nut 93. The upper portion ci the rod 89 is turned down and offers a stud tl, the function of which will be explained later on.

The rod 89 ishollow and slides on the stein 85. A cap. 95 loiers at its center, a boss 555, forced on the upper portion of the stem e5. This cap rnay completely surround the pump body 85x. Sil designates a spring bearing, on one hand, on the bottom of the recessed portion 5i of the part E!) and, on the other hand, on the cup shaped element 92. This spring pushes upwards the rod 39 and the leather washer 9i of the pump.

98,39 are the air vents of the pump. A capillary tube (not shown in the drawing) dipping into the liquid to be atomized, is screwed by its upper` portion into the tapped channel et. The atomizer stopper operates as follows:

The socket 'i5 being sealed on the neck of the phial containing the liquid to be atoinized, the atomizer, on which the capiilary tube is mounted, is screwed on it. The liquid rises, due to capillarity, up to the flared portion 1.3, going through the channel it. The cap e5 is then depressed; the air contained in the pump body, dfi is expelled by the leather washer @i into the channel M, goes through the pipe 18 and thence to the end part 19, atomizing the liquid thus carriedalon during its passage through the flared portion i3.

The cap 95 is released and resumes its position of rest under the action of the spring Si;

some air entersthe pump body through the holes 98, 99 and the phial through the passage provided between the parts Si) and 65 and the channel il. Some liquid again lls the ared portion i3. The atomizer is again ready for operation.

When it is desired to carry the phial provided with its atomizer stopper, a rotation of a quarter turn is imparted to the part iili, with respect to the part 65. The stud 32 then rnoves from the stud 89 to the stud di (Figure 5). This motion is possible since the connection between the parts 68 and 65 is effected by the spring 8i', which makes it iieXible. Further, in view of the carrying of the phial, the cap 95 is pushed in and is imparted a rotation of a quarter turn to house A pump body 8d is screwed on the the portion 89a of the rod 89 under `the upper wall of the pump body S4. The stud Se limits the rotation of the cap. The whole then assumes the shape shown in Figure '7.

When it is desired to again utilize the atomizer, the above'mentioned operations are effected in the reverse order.

The pipe 83 prevents the dust particles con tained in the pump body and falling downwards, from moving down in the channel is and thence towards the dared portion 13.

Various modcations may be made to the types of embodiment given by Way of examples, within the scope of the invention. Y
